Endeavour’s astronauts
– Commander Ken Cockrell, Pilot Paul Lockhart, Franklin Chang-Díaz,
Philippe Perrin, Dan Bursch, Yury Onufrienko and Carl Walz – were awakened
just before 4:30 Central time this morning to the National Anthem, in
honor of Flag Day today.

Working with the
International Space Station’s Expedition Five crew, Commander Valery
Korzun and Flight Engineers Peggy Whitson and Sergei Treschev, Endeavour’s
astronauts will deactivate the Leonardo Multi-Purpose Logistics Module
and will remove it from its location on the Unity node of the International
Space Station. Using the shuttle’s robotic arm, Cockrell will place
the module back into Endeavour’s cargo bay for its return to Earth.

About 5,600 pounds
of equipment and supplies are being left behind on the ISS, including
a new phone booth-sized rack to house delicate microgravity experiments
and a glovebox to provide the Expedition Five crew future hands-on interaction
with contained experiments. The cargo module is returning with 4,665
pounds of discarded equipment and supplies to Earth.

Last night, an
initial attempt to provide power from the newly installed Mobile Base
System platform to the space station robotic arm, Canadarm2, was not
successful. Engineers believe that a minor software glitch is preventing
commanding from the platform to reach the newly refurbished robotic
arm so that the new platform, rather than the Destiny Laboratory, can
provide power for the arm. This is not believed to be a serious problem,
and should be corrected well before the arm “walks off” its base location
on the Destiny to use the Mobile Base System as its formal platform
for a ride down the length of the station’s truss structure. Canadarm2
received a new wrist roll joint yesterday during the final spacewalk
of the flight by Chang-Díaz and Perrin, and the arm itself has full
functionality and redundancy.

Endeavour’s
steering jets are being used to raise the station’s altitude a
third and final time today prior to tomorrow’s scheduled undocking.
The three maneuvers are expected to raise the altitude of the ISS by
around six statute miles.

Endeavour is scheduled
to undock from the ISS Saturday morning at 9:32 a.m. Central time while
the two spacecraft fly over western Kazakhstan, not far from Russia’s
primary launch site at the Baikonur Cosmodrome. Once Endeavour departs,
ISS residents Korzun, Whitson and Treschev will begin their 4 ½
month mission in earnest, unpacking gear and settling in to their new
home in orbit.

All systems on
both Endeavour and the International Space Station continue to function
normally as the two craft orbit the Earth every 90 minutes at an altitude
of 240 statute miles. Endeavour is scheduled to undock from the space
station Saturday morning.

The next STS-111
status report will be issued Friday evening, or earlier, if events warrant.
